[Exim] Outlook 2000 and Express

Has anyone heard of any problems with using pop3 to check email with Outlook
2000 (from an Exim server)? When I POP mail using Outlook Express it works
just fine with no problems. Then, I try with Outlook 2000 and it connects,
disconnects, and doesn't download any mail (obviously, I'm testing this when
there is email in the mailbox). I've got the same server settings and
everything in both email clients - just not sure what could be causing this
to happen.

Thanks,
